Title: Disconnection diagnostic device for duty control solenoid
Inventor: MURAKI HIROKATA
IPC: F02D45/00
Filed: 1994-05-06
Abstract: PURPOSE:To conduct diagnosis on the presence of disconnection of a duty control solenoid driven by a duty signal with the on-time rate changed within a fixed duty control cycle (6.4ms). CONSTITUTION:A checking circuit for a solenoid is provided to lead out a check signal to be an H-level only at the time of no disconnection as well as a duty signal being in the off state. The check signal from the chekcing circuit is sampled in a sampling cycle (2.048ms) shorter than a duty control cycle, and the history of the sampled check signal is stored. Disconnection is diagnosed on the basis of the presence of the H-level history in the specified diagnosis delay time (51.2ms or more), but diagnosis is inhibited when the off- time rate of the duty signal is the specified lower limit value (15%) or less.

Title: Magnetic head and manufacture thereof
Inventor: GOTO MAKOTO
IPC: G11B5/127
Filed: 1989-04-14
Abstract: PURPOSE:To drastically decrease the influence of the pseudo gap at the boundary between magnetic cores and ferromagnetic metallic thin films by forming the joint surfaces between the ferromagnetic metallic alloy films and the ferrite cores as passive surfaces. CONSTITUTION:The I core 5 and the C core 6 are separately formed by using Mn-Zn ferrite and Cr is sputtered to 50 to 150Angstrom thickness on the joint surface of the I core 5 with a sputtering device. The O and Cr in the ferrite react and Cr2O3 is thereby partly formed. An Fe-Al-Si alloy layer is formed to 1 to 5mum thickness on the Cr layer in a nonoxidative atmosphere. This Cr is diffused into the Fe-Al-Si layer by a heat treatment to annihilate the Cr layer. The Fe-Al-Si layer 9 contg. the Cr is thereby brought into direct contact with the Cr oxide layer 12. This I core 5 is bonded by glass 7 to the C core 6. The glass having the softening point higher than the softening point used for fixing the magnetic head to a slider is used for this glass 7. The influence of the pseudo gap at the boundary between the magnetic cores and the metallic thin films is drastically decreased by the diffusion and annihilation of the Cr thin films.
